700 - mW的MONO低压音频功率放大器 700-mW MONO LOW-VOLTAGE AUDIO POWER AMPLIFIER
description
The TPA701 is a bridge-tied load BTL audio power amplifier developed especially for low-voltage applications where internal speakers are required. Operating with a 3.3-V supply, the TPA701 can deliver 250-mW of continuous power into a BTL 8-Ωload at less than 0.6% THD+N throughout voice band frequencies. Although this device is characterized out to 20 kHz, its operation was optimized for narrower band applications such as wireless communications.
